  1. Charger Hellcat (2015 +)
    Under heavy acceleration at high speed I always hear a clattering/rattle sound coming from engine, in front of glove box area. Sounds like valve-train type noise, or like engine knock, but highly doubt the latter since I always fill with Shell V-Power or BP Ultimate. Only happens while...
  2. Transmissions Gears & Diffs
    Hi, As the title states, lately I've been having an issue with the transmission coming out of gear under hard acceleration. After reading through the NAG1 (5-Speed) Automatic Transmission/TCM Refresher Info I believe I'm getting the "Loss of Drive" fault. It usually happens right at 5800 rpm...
  3. 300 General Discussion (2nd Gen - 2011 to 2014)
    My 300 SRT 2013 at around 60K and 1500 revs I lose all acceleration if going up a hill .I can press the pedal to the floor and nothing happens until suddenly it kicks in and takes off . Anyone having the same problem or have a fix?
  4. 300 General Discussion (1st Gen - 2005 to 2010)
    Upon first applying throttle from a stop the engine hesitates (rpms drop about 200, from 800 to 600) then the car acts like normal under the rest of acceleration. I have no trouble codes and it's not a misfire. Brand new air filter no obstructions of air flow going into the engine. Spark plugs...
  5. 300C, Magnum RT & Charger RT (5.7L V8)
    My buddy asked me a question that I'm not technically inclined to answer. He has a 2012 Ram pickup with a 5.7 Hemi. Has new coil, new injector, new spark plugs. Performed compression test run and it has a 150 psi. It does not skip on idle or at Cruise speed only under acceleration. Any help...
  6. The SRT-8 (6.1L and 6.4L V8)
    I recently went from a Corsa catback setup to an oem catback setup. The main goal was to reduce noise and drone. I wanted to compare the two to see if there is any change in performance. I don't have dyno sheets but I do have datalogs from my trinity which can provide acceleration times by...

  8. Magnum General Discussion (2005 - 2008)
    Hey guys and gals, i am polling around to see if a rear end swap from 2.82 gears to something else would give better acceleration from the get go. I have read articles of people swapping them out but i am looking for the best bang for buck.
  9. Magnum General Discussion (2005 - 2008)
    Hey guys im new here and need some help. My 06 Mag srt keeps going into limp mode. It does it every 35 miles if I'm going over 70 mph. I've noticed that I can drive 60 and under all day long and have no issues. What it is doing when I'm driving 70 and above for 35 miles or so is the lightning...

  11. General LX Discussion (1st Gen - 2005 to 2010)
    My 2005 Magnum R/T started throwing codes and intermittently stalling as well as accelerating on it's own last weekend. The shop gave the diagnosis of a bad throttle body. After replacing the throttle body the car still was having the same issue. It was taken to the dealership and I was told the...
  12. General LX Discussion (1st Gen - 2005 to 2010)
    I found this on MidWest Street Cars Site. Just letting you know I :threadjack: this one. Pretty Interesting. DEFINITION OF ACCELERATION - One top fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows of stock cars at the Daytona 500. - It takes just 15/100ths...
